Specification of Letters Patent.

Patented A11 29, 1911.

Application filed October 5, 1910. Serial No. 585,446.

To all whom it may concern:

Be it known that l, lVILLuM A. Bu CI-IANAN, citizen of the UnitedStates, rcsid ing at Asheville, in the county of liuncombe and State ofNorth Carolina, have invented certain new and useful In'iprovements inNeck-Yoke Couplings, of which the following is a specification.

This invention relates to harness and has particular reference to animproved coupling adaptable to neck yokes of double ha 1'- ness.

An object of this invention is to provide an improved coupling by meansof which the connecting ring may be removed from the end of the crossbar or neck yoke, and which when locked in position cannot beaccidentally displaced.

The invention has for another object to provide a coupling of thischaracter which is of substantial form and which is made up of but fewoperating parts so as to provide a device which may be economicallymanufactured.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which:-

Figure 1 is a perspective view of one end of the neck yoke disclosingthe improved coupling, and Fig. 2 is a transverse section through theend of the neck yoke showing the improved coupling in an open position.

Corresponding and like parts are referred to in the followingdescription and indicated in all of the views of the accompanyingdrawing by the same reference charao I ters.

Referring to the drawing, the numeral 10 designates the neck yoke whichis provided upon one end with a ferrule 11. The ferrule 11 is securedupon the neck yoke 10 in any suitable manner, preferably by screws 12which are countersunk in the outer face of the ferrule 11 and extendinto the neck yoke 10. The outer end of the ferrule 11 is provided witha depending and hinged arm 1.3, the rounded shank or inner end 14:thereof passing snugly and diametrically through the ferrule 11 andbeing enlarged as at 15, upon its extremity to prevent the displacementof the same. The rounded form of the inner end of the arm 18 admits ofthe turning of the arm beneath the ferrule 11 as desired. A lip 16 isformed upon the outer extremity of the arm 13 and is enlarged for thereception of the thumb of the operat orthereagniust, A lug l7 dependsfrom the inner end of the ferrule 11 immediately above the arm 13 and isprovided with a [)l'OjQtttlOll 18 at one edge to form a shoulder for thereception of the arm 13. The projection 18 forms a stop to limit theswinging movement of the arm 13 when closing the coupling.

A. leaf spring 90 is attached to the forward side of the ferrule 11 byrivets 21, or the like, and extends downwardly at substantially atangent to the surface of the ferrule 11 where it is curved inwardlybeneath thelug 17. The lower end of the leaf spring 20 rests against thelower edge of the arm 13, the spring 20 being provided with a transversedepression 22 for the reception of the arm 13. The depression 22 forms ashoulder for the retention of the arm 18 against the stop or projection18 when the coupling is closed.

The ferrule 11 receives a connecting ring 23, of any approved form, bymeans of which the haincs or collars of the harness are attached to theneck yoke 10.

T11 the operation of the improved coupling, when it is desired torelease the ring 23 from the ferrule 11, the operator presses the thumbagainst the lip 16 and the finger against the outer curved extremity ofthe leaf spring 20. \Vhen the leaf spring 20 is moved down to free thearm 13 from the depression 22, the arm 13 is then swung outwardly fromthe stop 18 into the position disclosed in Fig. 2.

It will of course be understood that this improved coupling may be usedin connection with other parts of the harness or applied to variousdevices without departing from the spirit of the invention,

Having thus described my invention, what is claimed as new is:

1. A. neck yoke coupling including a forrule for engagement over the endof a neck yoke and having a depending lug upon its inner end provided atone edge with a projection to form a shoulder at the lower end of thelug, a leaf spring carried against the side of the ferrule and having acurved lower end passing in registration beneath the lug, and a hingedarm carried upon the outer end of the ferrule for engagement between theshoulder and said spring.

2. A neck yoke coupling including a ferrule for engagement over theextremity of a neck yoke, a depending arm mounted for depression in itsinner face for the reception horizontal swinging movement beneath the ofthe arm. 10 ferrule, 21 lug depending from the inner end In testimonywhereof, I afiix my signaof the ferrule and having a shoulder formedture in presence of tWo Witnesses.
